Red Seal Glazier Practice Exam

What is a common problem that can occur due to improper glass installation?

1. Water leakage during rainfall

2. Window frames warping over time

3. Air leakage leading to energy loss

4. Glass becoming brittle prematurely

The correct answer is: Air leakage leading to energy loss

Air leakage leading to energy loss is indeed a common issue that can arise from improper glass installation. When glass is not fitted correctly within its frame, gaps can form at the edges. These gaps allow air to flow in and out of the building, undermining the energy efficiency of the structure. This uncontrolled airflow can lead to higher heating and cooling costs, as systems must work harder to maintain comfortable indoor temperatures. When the glass isn't sealed or installed properly, it can fail to create an airtight barrier, resulting in significant energy loss, especially in climates with extreme temperatures. This problem can also contribute to drafts and discomfort within living spaces. Ensuring a proper installation can help maintain the integrity of the building envelope and improve its overall energy performance. While water leakage, window frame warping, and glass brittleness are possible issues related to poor installation, they tend to arise under different circumstances and may not be as directly linked to how the glass itself was placed and sealed in its framing.
